Device and method for a wireless network

Abstract

The present invention provides a device for a wireless network comprising a single primary channel having a first predefined bandwidth configured as a common channel of operation for one or more devices associated with a specific access point, and a plurality of secondary channels having a second predefined bandwidth within the first predefined bandwidth. The device is configured to execute a first Carrier-Sense Multiple Access with Collision Avoidance, CSMA / CA, instance associated with the primary channel to gain access to the primary channel, wherein a first back-off is generated; and execute a second CSMA / CA instance associated with one of the secondary channels to gain access to the secondary channel, wherein a second back-off is generated.

Description

technical field [0001] The present disclosure relates generally to the field of wireless communications, and more particularly, to accessing channels in wireless communications networks. To this end, an apparatus for a wireless network comprising a single primary channel and multiple secondary channels and a method performed by the apparatus are disclosed. The single primary channel has a first predefined bandwidth and is configured as a common operating channel for one or more devices associated with a particular access point, and the plurality of secondary channels have a first predefined bandwidth within the first predefined bandwidth. Two predefined bandwidth. Background technique [0002] In general, applications that increasingly use wireless channels require high throughput and ultra-low latency. For example, virtual reality (Virtual Reality, VR) games generally require 20 milliseconds as the maximum acceptable delay for high-quality user experience. In addition, W...

Problems solved by technology

While this approach can reduce latency, it suffers from two major problems: implementation complexity is relatively high (requiring multiple receive chains), and the state of each primary channel limits channel access for the entire BW

[0007] The disadvantage of traditional devices and methods is that they have limited efficiency or greatly increased complexity

Also, when keeping rules based on the primary channel, the available BW cannot be used if the primary channel is busy
